1. Install antlr4 exactly like described under Quick start: http://www.antlr.org/
2. pip install antlr4-python2-runtime
3. pip install pystache
4. Generate python parser / lexer for NaCl.g4 grammar WITH visitor (NaClVisitor.py): antlr4 -Dlanguage=Python2 NaCl.g4 -visitor
5. Make transpiler program executable: chmod u+x NaCl.py
6. run with cat examples/nacl.nacl | ./NaCl.py
7. For testing, using the grun program (alias really) is nice. This requires that you generate the java lexer / parser
8. antlr4 NaCl.g4 && javac NaCl*.java
9. cat examples/nacl.nacl | grun NaCl prog -gui
